I did not model extended senses or adrenal glands as I hate the look of the bits of plastic that are supposed to indicate them. For wysiwig, I just consider them to be internal evolutions.
Why I Started This Army
Back in second edition, I bought loads and loads of Tyranids and never painted a thing beyond 3 gaunts with spike rifles. I wanted to prove to myself that I could paint up a tyranid force so put together a simple list (back in 4th edition 40k) and bought all the models. The ripper swarms were so boring to paint that I almost gave up completely, but I persevered and finally completed the army. I used a faster, sloppier painting style than usual so that I can quickly add troops in the future if needs be, and being a horde army, I did not want a paint scheme that would take forever to do. All in all, this army serves as a solid core if I want to expand it in the future, but it is not very well suited to 5th edition game play as it stands right now. It looks good in my display cabinet though, and the colours blend together well, giving a good overall impact.
